TABLE 1 formulation and Properties of the examples and comparative examples (parts by weight)
Note: the PP resins in the table are blends of homopolymeric PP and copolymeric PP in a ratio of 6: 1. The homopolymerized PP can be selected from T30S, V30G, Y600, K1008, 1100 and 1120, and the like, and the copolymerized PP can be selected from K8003, K7726, K7926, K8025, K9927, and the like.
The compatible toughening agent is POE grafted maleic anhydride.
The halogen-free flame retardant is melamine polyphosphate. The flame retardant is replaced by one or more than one of melamine cyanurate, alkyl hypophosphite, ammonium polyphosphate and piperazine pyrophosphate system compound flame retardants, and has the same effect.
The hollow glass beads are U.S. 3M H20/1000 hollow glass beads. The same effect is also achieved by replacing H50/1000 hollow glass microspheres.
The whisker material is silicon carbide whisker. The same effect can be achieved by replacing any one or a combination of more of silicon nitride whisker, mullite whisker, potassium titanate whisker, aluminum borate whisker, magnesium oxide whisker, calcium sulfate whisker, calcium carbonate whisker or magnesium salt whisker. .
The lubricant is polyethylene wax. Replacing one or the combination of ethylene bis stearamide, silicone powder and erucamide.
The antioxidant is antioxidant 264. The same effect can be obtained by replacing any one or a combination of at least two of the antioxidant CA, the antioxidant 2246, the antioxidant 3114 and the antioxidant 3125. .
The toner is FMR-65-AO of Shenzhen Qiansheng New Material science and technology Limited. The same effect can be achieved by replacing Clariant PV Fast Yellow HG and PV Fast Green GNX, Shenzhen Qiansheng New Material science and technology Limited FMR-65-AOTBB-50.
As can be seen from the comparison between example 1 and comparative example 1, the glow wire ignition temperature of the PP material is not passed at 850 ℃ without adding the hollow glass beads, the flame retardant rating is V2, and the toughness and strength of the material are reduced. The hollow glass beads and the halogen-free flame retardant are compounded, so that a carbon layer can be promoted to be formed, the effects of insulating heat and slowing down the escape of combustible gas are achieved, and the flame retardant property is improved.
The comparison between the example 1 and the comparative example 2 shows that the whisker material is not added, the comprehensive performance of the material is the worst, which shows that the whisker material is added to exert the reinforcing effect on the matrix to the maximum extent, and the compatible toughening agent is also added to improve the compatibility of the whisker material and the polypropylene matrix, improve the toughness and the strength performance of the product, and simultaneously ensure that the prepared flame-retardant PP material has high-temperature resistance, the strength and the integrity of the flame-retardant PP material cannot be changed at high temperature, and the ball pressure temperature and the glow wire ignition temperature of the product are improved.
As can be seen from the comparison between the example 1 and the comparative example 3, the PP material has no color change effect and cannot play a warning role when the temperature reaches a certain degree without adding the temperature sensitive toner, so that the scald is easily caused. When the socket and the charging head prepared from the thermochromic PP material are placed in an inappropriate installation environment and in an overcurrent state to cause an overheat state, the material can change into a preset color in response to a preset heat-resistant temperature range so as to play a role in warning, and potential safety hazards are eliminated.
